Level of comfort and support
Having previously slept on a medium firmness mattress with padding and a feather bed too, I woke up everyday sore. We opted for a firm mattress replacement. WOW, what a difference! While I have to admit at first the level of support has taken me some time to get accustomed to. I will say that it has provided me for some great nights sleep. The textured surface allows for air to channel giving it some level of cooling. While it is a memory foam and you should let it "breathe" for a day or two after unwrapping, the odor dissipates rather swiftly. I have not noticed any sagging and feel like I am in a new bed every night.
